Affiliates of the Iraqi terror group Islamic State of Iraq and the Levant (ISIL), also known as ISIS, are praising and potentially recruiting extremists based on controversial tweets by a senior Department of Homeland Security (DHS) adviser who recently claimed that ISIL is proof that a Muslim "caliphate" is making an "inevitable" return.

The recent tweets by Mohamed Elibiary, a controversial figure who serves as a senior member of DHS' Homeland Security Advisory Council (HSAC), were recently picked up in the Arabic press and widely disseminated on Twitter by multiple Islamic extremists.

Elibiary's tweets—which disparaged Americans as showing "belligerence" after the 9/11 terror attacks and told of the "inevitable" return of the Muslim caliphate—drew widespread criticism online and prompted calls for his removal from DHS' advisory committee.
